‘Unlimited Attack Vectors’—All Windows Versions At Risk From New Flaw

Microsoft is facing a significant security vulnerability in its Windows operating system known as PhantomRPC, which allows for privilege escalation. Cybersecurity experts have expressed concern over the company's delayed response in issuing a patch for this flaw. The vulnerability resides within the Windows Remote Procedure Call (RPC) architecture and enables processes with impersonation privileges to elevate their permissions to SYSTEM level. Researcher Haidar Kabibo identified five distinct paths for exploitation, which require user interaction, coercion, or compromise of background services. Despite disclosing the vulnerability to Microsoft in September 2025, the company categorized it as moderately severe and did not issue a patch or a Common Vulnerabilities and Exposures (CVE) listing. Microsoft stated that the technique requires an already-compromised machine and emphasized the importance of following security best practices. Experts have criticized Microsoft's lack of action, arguing that it is operationally negligent and places the burden of risk management on users. In the absence of a patch, security professionals recommend focusing on access control and environmental hygiene to mitigate the risks associated with the vulnerability.

How to Reset Folder Permissions in Windows 11: 5 Proven Methods That Actually Work

Folder permissions in Windows 11 control access to files, determining who can read, modify, or delete them. Common issues arise from drive or file migration, Windows updates, malware, or user errors. Symptoms include "Access Denied" messages and ownership displayed as "unknown." Methods to resolve folder permission issues include: 1. Security Tab: Reset permissions through the Security tab by modifying access levels and ensuring proper inheritance. 2. Take Ownership: Claim ownership of a folder if the current owner is no longer valid, then reset permissions. 3. Command Prompt: Use commands like PLACEHOLDERfa5c045a85bc6cf0 and PLACEHOLDER14a87b7576573f58 to reset permissions quickly and efficiently. 4. PowerShell: Utilize PowerShell for advanced permission resets, allowing for conditional logic. 5. Windows Reset: As a last resort, reset Windows to restore default permissions while keeping personal files. To prevent future issues, back up permissions before changes, understand NTFS vs. share permissions, and avoid altering system folders. If problems persist, ensure commands are run as an administrator, check ownership settings, and verify that Group Policy or sync tools are not overriding changes.
